Could you check them for me and change them if incorrect. Please help me. Not sure if I am getting the right answers. Using the standard normal distribution, find each probability:
P( z >1.66) = 0.9515
P(z < -2.03) = 0.0212
P( z > -1.19) = 0.1170
P( z < 1.93) = 0.9732
P ( z > -1.77) = 0.0384
+23254 Your answer for the second an fourth problems are correct (the one that have a "<" sign).
The other problems are incorrect because the calculator that you are using (or the way that you are using it) gives answers for "<"; to get answers for ">", subtract that answer from 1.0000.
For example, your last answer, 0.0384, should be subtracted from 1.0000 to get 0.9616. This is also true for problems 1 and 3.
